HELPING (AUXILIARY) VERBS

  • Auxiliary verbs add functional or grammatical meaning to the clause in which they are used. They provide the main semantic content of the clause. The positive, negative or interrogative function of sentences are also defined by these auxiliary verbs.

  • In sentences constructed in present simple and past simple tenses, we cannot use any auxiliary verbs. Negative and interrogative sentences can be used with the auxiliary verbs “do”, “does” and “did.”

Present simple tense:

Past simple tense:

They played football yesterday.

They didn’t play football yesterday.

  • “Do”, “does” and “did” can be used as regular verbs as well.

I do housework on Sundays.

I don’t do housework on Sundays.

They did shopping yesterday.

  • For all perfect tenses, we have to use V3 (gone, written, played, etc.) after the auxiliary verb (have, has, had)

He’s gone abroad.

 

  • For all continuous tenses, we use the form “be + V-ing”
